It's an easy call, TRADE DOWN.
Outside of Wall and Turner, all the rest of the top picks could end up being great players or complete busts.
It does nothing for us to go to all the work and sacrifice to trade up to end up with a project or bomb.
Might as well increase our chances and go with two picks. Might as well get to average/good players than one star/bust IMO.
Get a good solid wing that can shoot, create with Deron, and play some defense. And get a shotblocking big man. For me, a draft with Pau George, Aminu, Henry, or Babbit. Combined with the big man selection of Aldrich, Davis, Sanders, or Whiteside would be good enough for me.
IMO two good players like one of those wings mentioned above combined with one of those big men mentioned above would be better than selling the farm to get one player. We should address both our overall athleticism, length, shooting, and shot blocking in this draft. Doing so will require multiple picks.
